What Are the Reasons Why the Car Doesn't Respond When the Key Is Pressed?

[KeeganLynn]

The reasons why the car doesn't respond when the key is pressed include: 1. The remote key battery is dead or the car battery is dead; 2. There is strong signal interference around, and you can use the hidden mechanical key inside the remote key to open the car door. Here is more information: 1. If even the mechanical key cannot open the car door, it may be that the car's central locking system is in an electronic lock state. You need to wait for one or two hours for the lock to be released before trying to unlock it again. 2. The remote key refers to a key that can open and lock the door remotely without inserting the key into the lock hole. It emits a weak radio wave from the owner, which is received by the car antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator (motor or electromagnetic coil) performs the action of unlocking or locking. The system mainly consists of two parts: the transmitter and the receiver.
